The accumulation of microplastics and their associated heavy metals on the surfaces of microplastics in various tissues of the pelagic fish Rastrelliger kanagurta, from the northern coast of Central Java, Indonesia
Researchers examined microplastic contamination in the tissues of pelagic mackerel from the northern coast of Central Java, Indonesia. The study found microplastics predominantly in fragment shapes smaller than 500 micrometers across gills, stomach, intestines, and liver, along with seven polymer types, multiple plastic additives, and heavy metals including manganese, chromium, and nickel adsorbed onto microplastic surfaces.
Bioaccumulation and Bioremediation of Heavy Metals in Fishes—A Review
This review summarizes how heavy metals accumulate in fish tissues through contaminated water and enter the human food chain, posing serious public health concerns. The paper discusses bioremediation techniques using microorganisms and other methods to remove heavy metals from aquatic environments, which is relevant because microplastics can carry and concentrate these same toxic metals.
Heavy Metals Concentration in Sardina pilchardus (Walbaum, 1792) from the Moroccan Mediterranean Coast and Potential Human Health Risk Assessment
Researchers assessed heavy metal concentrations in sardines from the Moroccan Mediterranean coast and found spatiotemporal variations in toxic metal accumulation, with health risk assessments indicating generally safe levels for human consumption.
Suspected microplastics in Atlantic horse mackerel fish (Trachurus trachurus) captured in Portugal
Researchers examined microplastic presence in multiple internal organs of Atlantic horse mackerel caught off the coast of Portugal. The study found suspected microplastics in all organs examined, including gills, gut, kidney, and heart, with the smallest particles found in the heart and blood, highlighting the potential for microplastics to translocate beyond the digestive system.
Heavy metals and microplastics in the stomach contents of two fish species: Trachurus trachurus and Zeus faber along the North and Central Atlantic Coast of Morocco
Scientists examined the stomachs of two popular commercial fish species along the Moroccan Atlantic coast and found microplastics in 46% of the fish, mostly in the form of fibers made from polyamide, polystyrene, and acrylic. Heavy metals like mercury, cadmium, and zinc were also detected in 97% of samples, though levels stayed below regulatory limits. While the contamination risk from microplastics was generally low, the study flagged potential health concerns for children who frequently eat these fish.
Ecological and health risk assessment of heavy metals bioaccumulation in Ganges fish near Varanasi, India
Not relevant to microplastics — this study measured heavy metal (lead, manganese, chromium, cadmium) contamination in the Ganges River at Varanasi and in fish caught there for human consumption, finding metal levels well above safe drinking water standards and significant bioaccumulation in fish tissue.
Histopathological alteration in the liver of Sardinella longiceps as a biomarker of heavy metal pollution in aquatic ecosystem.

Mercury Biogeochemistry and Biomagnification in the Mediterranean Sea: Current Knowledge and Future Prospects in the Context of Climate Change
This review examines mercury contamination in the Mediterranean Sea, where fish contain much higher mercury levels than Atlantic species, mainly due to environmental conditions that promote conversion of mercury into its most toxic form. Climate change is expected to worsen the problem by altering the marine food web in ways that increase mercury accumulation in predatory fish like tuna. While focused on mercury, the findings are relevant to microplastics research because microplastics can absorb and transport mercury and other heavy metals through aquatic food chains.
Total Mercury (THg) Content in Red Mullet (Mullus barbatus) from Adriatic Sea (Central Mediterranean Sea): Relation to Biological Parameters, Sampling Area and Human Health Risk Assessment
Total mercury content was measured in muscle tissue of red mullet from 16 sampling pools across the Adriatic Sea, with an overall mean of 0.20 mg per kilogram wet weight.
